numpy.log10(arr, out = None, *, where = True, casting = ‘same_kind’, order = ‘K’, dtype = None, ufunc ‘log10’) : This mathematical function helps user to calculate Base-10 logarithm of x where x belongs to all the input array elements.
array : [array_like]Input array or object. out : [ndarray, optional]Output array with same dimensions as Input array, placed with result. **kwargs : allows you to pass keyword variable length of argument to a function. It is used when we want to handle named argument in a function. where : [array_like, optional]True value means to calculate the universal functions(ufunc) at that position, False value means to leave the value in the output alone.
An array with Base-10 logarithmic value of x; where x belongs to all elements of input array.
Code 1 : Working
Input array : [1, 3, 5, 100000000] Output array : [ 0. 0.47712125 0.69897 8. ] np.log10(4**4) : 8.0 np.log10(2**8) : 8.0
Code 2 : Graphical representation
out_array : [ 0. 0.30103 0.47712125 0.60205999 0.69897 ]
